Virtuelle Maschinen: zSeries- und S/390-Partitionierung     

Joachim von Buttlar  Wilhelm G. Spruth 《Informatik - Forschung und Entwicklung》2004,39(1):41-54

Der gleichzeitige Betrieb mehrerer Gast-Betriebssysteme auf einem einzigen physischen Rechner unter einem Host-Betriebssystem ist eine leistungsfähige moderne Entwicklung. Bekannte Beispiele sind VMware für die IA32-Architektur sowie das Betriebssystem z/VM und die PR/SM-LPAR Einrichtungen der zSeries-Architektur. Die Nutzung eines Betriebssystems als Gast bedingt einen Leistungsverlust. Die als Partitionierung bezeichnete Zuordnung von Systemressourcen zu den einzelnen Gast-Betriebssysteme ist schwierig, wenn eine dynamische Anpassung an sich ändernde Lastprofile erforderlich ist. Diese Probleme lassen sich mittels Erweiterungen der Hardwarearchitektur adressieren, sowie durch Softwarestrukturen, welche diese Erweiterungen nutzen. Die Erweiterungen der Hardwarearchitektur gehen über das hinaus, was auf heutigen Rechnerarchitekturen wie IA32 oder Mips verfügbar ist. Der vorliegende Beitrag erläutert den optimalen Betrieb von Gast-Betriebssystemen und die begleitenden Partitionierungsmöglichkeiten auf der zSeries-Plattform und beschreibt die zusätzlichen Hardware- und Software-Einrichtungen, welche dies ermöglichen.  相似文献

Acquiring Clinical Knowledge from an Online Video Platform: A Randomized Controlled Experiment on the Relevance of Integrating Anatomical Information and Clinical Practice     

Johannes Grosser  Martina Bientzle  Thomas Shiozawa  Bernhard Hirt  Joachim Kimmerle 《Anatomical sciences education》2019,12(5):478-484

Basic subjects in medical education, such as anatomy, are often taught through teaching formats that do not always sufficiently demonstrate the relevance of this basic information for clinical practice. Accordingly, it is a recent trend in anatomy education to link anatomical information more explicitly to clinical practice. This article presents an online video platform (Tuebingen’s Sectio Chirurgica [TSC]) as one means of explicitly integrating preclinical anatomical knowledge and clinical application. The purpose of the study presented here was to examine the effects of videos through which medical students were educated about Anterior Cruciate Ligament reconstruction. A TSC video about this surgical procedure was compared to a video with a traditional lecture providing the identical information. Participants (n = 114) perceived the TSC video to be superior in comprehensibility of the presentation (P = 0.003) and conceivability of the surgical procedure (P = 0.027), and to be more entertaining (P < 0.001). Moreover, participants in the TSC condition acquired more clinical knowledge than in the lecture condition (P = 0.043) but did not differ in their acquisition of anatomical knowledge. Mediation analyses indicated that the effect on the acquisition of clinical knowledge was mediated by comprehensibility, conceivability, and entertainment. These findings are discussed regarding their implications for medical education in terms of contributing to the general trend of linking preclinical anatomical knowledge to clinical application. A discussion about the limitations of the study and suggestions for future research are also provided.  相似文献   

Breaking the Cycle: Future Faculty Begin Teaching with Learner-Centered Strategies after Professional Development     

Diane Ebert-May  Terry L. Derting  Timothy P. Henkel  Jessica Middlemis Maher  Jennifer L. Momsen  Bryan Arnold  Heather A. Passmore 《CBE life sciences education》2015,14(2)

The availability of reliable evidence for teaching practices after professional development is limited across science, technology, engineering, and mathematics disciplines, making the identification of professional development “best practices” and effective models for change difficult. We aimed to determine the extent to which postdoctoral fellows (i.e., future biology faculty) believed in and implemented evidence-based pedagogies after completion of a 2-yr professional development program, Faculty Institutes for Reforming Science Teaching (FIRST IV). Postdocs (PDs) attended a 2-yr training program during which they completed self-report assessments of their beliefs about teaching and gains in pedagogical knowledge and experience, and they provided copies of class assessments and video recordings of their teaching. The PDs reported greater use of learner-centered compared with teacher-centered strategies. These data were consistent with the results of expert reviews of teaching videos. The majority of PDs (86%) received video ratings that documented active engagement of students and implementation of learner-centered classrooms. Despite practice of higher-level cognition in class sessions, the items used by the PDs on their assessments of learning focused on lower-level cognitive skills. We attributed the high success of the FIRST IV program to our focus on inexperienced teachers, an iterative process of teaching practice and reflection, and development of and teaching a full course.  相似文献

Teachers' conceptualization of pupil control in elementary school physical education   总被引：1，自引：0，他引：1  

S A Henkel 《Research quarterly for exercise and sport》1991,62(1):52-60

Management of conduct has been considered the most important problem facing schools in America during 16 of the last 20 years (Gallup, 1988). Yet little is known about specific techniques teachers use to achieve pupil control in physical education. One purpose of this work is to describe the development of a conceptual framework for pupil control techniques. The framework was derived from 64 live observations and audiotapes of elementary school physical education lessons. A second purpose is to describe how teachers may potentially foster pupil self-control. Data were reduced through analytic induction, constant comparison, and topological analysis. The investigator placed 23 categories into three classifications as perceived by teachers: anticipatory, tutorial, and punitive. Teachers confirmed frequency of using techniques during interviews and on surveys. Intraobserver agreement tests yielded 88% for distinguishing among categories. Interobserver scores ranged from 83 to 86% agreement. Categories may serve to increase teachers' repertoire of control techniques in accordance with their ideological beliefs. For teachers in this study, facilitating self-control involves (a) selecting tutorial control techniques, (b) using indirect forms of techniques, and (c) conveying reasons for using techniques.  相似文献   

Rediscovering the political dimension of the personal life story: results from an intergenerational narrative learning project with older adults in South Westphalia     

Joachim Broecher  Joyce H. Davis  Janet F. Painter 《International Journal of Lifelong Education》2017,36(4):471-485

Using qualitative interviews, focus groups, storytelling and collective journaling, the life experiences of people in a local village community, in South Westphalia, Germany, born between 1930 and 1945, were analysed collaboratively. The research intention was to give the younger generations in that region access to these experiences and insights, within the context of democratic learning and civic education. The focus of this narrative learning project was on the politically relevant issues and themes they contained, above all: the significance of free information and thought, a free cultural life, access to education for all children and youth, a self-determined life for women and girls, as well as cohesion and self-help structures in the social community. Many tales were shared from the Third Reich, making references to Wilhelmine Germany and the Republic of Weimar, including how these times had been narrated to them through their forebearers and families’ archives.  相似文献   

Soziale Ungleichheit beim Zugang in eine Berufsausbildung: Welche Bedeutung haben die Institutionen?     

Mona Granato  Joachim Gerd Ulrich 《Zeitschrift für Erziehungswissenschaft》2014,17(2):205-232

The corporatistic governance model of nonacademic vocational training, which is predominant in Germany, has produced heterogeneous and complex conditions for the access to vocational training. Which training programs are offered and the selection of applicants is largely determined by the training companies themselves. Adolescents interested in vocational training are thus confronted with diverse admission requirements. Which resources they can and have to use in order to receive a training position is significantly determined by the respective admission requirements. The present paper elucidates key institutional conditions of the access to vocational training which can serve as explanations for the (re-)production of social inequalities in the transition process from school to vocational training. In particular, the inequalities with respect the admission to vocation training along the lines of educational degrees, gender, as well as regional, social, and ethnic backgrounds are investigated.  相似文献
